VT Special Sequences
VT mode string formats are different to allow for special characters such as control characters and escape sequences. Enter Escape and binary codes in C-style syntax using the backslash character (\). The system treats in-line spaces as part of the sequence.
The sequence \xhh lets you specify any ASCII character as a hexadecimal character code. For example, you can give the ASCII backspace character as the normal C escape sequence (\b), or you can code it as \x08 hexadecimal.
You must use at least one digit for a hexadecimal escape sequence, but you can omit the second digit. Therefore, you can specify the hexadecimal escape sequence for the backspace as either \x8 or \x08.
